Hello,
You can disable automatic updates in WordPress by adding this line of code in your wp-config.php file:
define( 'WP_AUTO_UPDATE_CORE', false );
If you want to receive minor core updates but disable theme and plugin updates, you can do so by adding the following code in your theme’s functions.php file.
Disable automatic WordPress plugin updates:
add_filter( 'auto_update_plugin', '__return_false' );
Disable automatic WordPress theme updates:
add_filter( 'auto_update_theme', '__return_false' );
